What Do Sturgeons Eat?
Posted In: Fish.
Beware of the sturgeon! Yes, that’s right, you truly need to beware. In recent years, there have been warnings issued to individuals living along the Florida coastline that jumping sturgeon could cause serious bodily harm or injury. The sturgeon themselves are not hostile creatures, and they are not jumping to hurt anyone. It’s just something that they have done for years, a behavior trait, but one that must be taken into consideration while boating in and around Florida waters.
Case in point, a woman in Florida in 2011 broke her leg when a 70 pound sturgeon suddenly jumped out of the water, into her boat, and broke her leg. So, you see sturgeons certainly can be dangerous, even if the chances of that happening are small.
There are 26 species of sturgeons worldwide. The four common ones are the white sturgeon (Acipenser transmontanus), the Atlantic sturgeon (Acipenser oxyrinchus), the Beluga or European sturgeon (Huso huso) & the lake sturgeon (Acipenser fulvescens).
Oldest species of fish
Sturgeons are one of the oldest species of fish in existence on the planet Earth, with the fossil record indicating that the species is at least 200 million years old. It is second only to the coelacanths, which is 400 millions years old. Sturgeon are a formidable fish, they live approximately 60 years, can grow in length up to 15 feet and can weigh in excess of 800 pounds. In other words, they are about the size of a small car. How would you like it if one of those suddenly jumped out of the water and struck you? I’m sure you wouldn’t want that to happen.
What do these giants eat?
Sturgeon mainly feed on small organisms when they are just babies, when they grow up they start to eat all kinds of things. They are known to eat dead fish and when swimming in the river areas, mollusks, crustaceans and lampreys, an eel which comes to spawn at the same time that the sturgeon come to spawn, are often on the menu.
From oceans to rivers
In open waters, particularly near ocean inlets, the sturgeon will eat smelt and shad. When the large swarms of smaller fish enter into the river systems, they provide an ample source of the sturgeon.
Properly cooked, the sturgeon is an edible food source for humans but they must be cooked properly, de-skinned and cook thoroughly. Fishermen fish sturgeon along the rivers in America, but sturgeons are not a particularly tasty fish, and there are other fish species that taste better within the same fishing waters.
They lay a lot of eggs
Sturgeon have the ability to spawn sheer numbers of eggs. The female sturgeon lays approximately 800,000 to 4,000,000 eggs per year during the spawn. Despite this, the sturgeon remains a species under threat.
The most popular and practical commercial use for sturgeons is actually the production of caviar from sturgeons located in the Caspian Sea. This caviar can be frightfully expensive and is highly prized the world over. I personally love the stuff. I usually buy it for family get-togethers, weddings or other festive events. A small bottle of sturgeon caviar, perhaps 2 to 4 ounces, may cost upwards of $200 or more.
They will be around for a long time
Sturgeon will probably continue to be around for a long time. They have been around much longer than man, and there is a good chance still be around much longer after man is gone. However, we still need to be careful that we don’t wipe out the sturgeon population, and that will require man to be responsible regarding their sturgeon cultivation and usage.
